Fluffeh writes: "Two rulings in related cases this week have dealt a serious blow to the plaintiffs and their dodgy legal strategy. Ordinarily, copyright law is handled by the federal courts, but Florida plaintiffs have begun using an obscure provision of state law called a "pure bill of discovery" to attempt to force ISPs to reveal the identity of suspected file-sharers. The rulings, one on Monday and one on Wednesday, saw two different judges siding with the objecting ISPs. These back-to-back rulings against the plaintiffs suggest that they're likely to lose any time ISPs raise objections to fishing expeditions against their customers."
